Access Point Frequency Allocation Using Distributed Usage Records
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems using millimeter wave and terahertz frequency bands, the small coverage area of access network devices leads to low communication efficiency due to the centralized allocation of frequency resources in 5G and pre-5G systems.
Innovation Solution
Implementing a distributed resource management method where access point devices determine their operating frequencies based on frequency usage record information, allowing them to select frequencies that are not occupied by other devices, thereby optimizing frequency allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centralized scheduling is used for frequency resource allocation in 5G and pre-5G systems, then frequency resources can be managed uniformly, but communication efficiency decreases due to small coverage area of access network devices
Solution Approach 1:
The patent segments the centralized scheduling function into distributed autonomous decision-making at each access point device. Each access point independently determines its operating frequency based on local frequency usage records, eliminating the need for complex centralized coordination while improving communication efficiency in millimeter wave and terahertz bands.
Solution Approach 2:
Access point devices perform self-service frequency selection by autonomously determining their operating frequencies based on locally stored frequency usage records. This self-organizing mechanism eliminates dependency on centralized scheduling, reducing system complexity while maintaining high communication efficiency in small coverage area scenarios.
2Productivity
If access network devices use small coverage area for millimeter wave and terahertz frequency bands, then frequency resource conflicts are reduced, but communication efficiency becomes low due to centralized allocation limitations
Solution Approach 1:
Each access point device autonomously selects its operating frequency by consulting local frequency usage records, making the frequency selection process simple and intuitive. This self-service approach improves ease of operation while simultaneously enhancing communication efficiency through distributed decision-making that adapts to small coverage area constraints.
3Adaptability or versatility
If frequency resources are pre-configured and centrally scheduled, then system control is simplified, but frequency allocation does not adapt to dynamic usage patterns in high frequency bands
Solution Approach 1:
The patent implements dynamic frequency allocation where access point devices continuously update frequency usage records and adapt their operating frequencies in real-time. This dynamic self-adjusting mechanism improves adaptability to changing usage patterns in millimeter wave and terahertz bands while keeping the overall system structure simple through distributed intelligence.
